To all whom t may concern.'

Be it known that I, JACOB B'o'cnnn, a citi zen of the Empire of Germany, residing at Caster, near Bedburg, Rhenish Prussia, in the Empire of Germany, have invented a new and useful 'Beet-Harvester, of which the following is a specification.

'This invention relates to a beet harvester of novel construct-ion, the present application being a division of a patent application filed by ine-July 31st. 1912 under Serial No. 712,456. That application embraces a beet harvester for cutting the .tops of the beets and separately collecting the tops and the roots, while the present application relates more particularly to means for loosening the soil around the roots and lifting the latter to such a height that they may be lifted, such loosening andf lifting means forming the subject'matter of the present application and being as follows: A lever 100 (Fig. 2)V is lmounted in the machine frame to rock at '1300? (Fig. 1) in* the vertical plane of th'e row of beets 2011, the `tops of which have been cut ofi'. The free end of the lever100 is guided between two suitvable parts v133, 133 of the machine frame and is shown as connected with a head 215, which is suspended from a disk 102 by means of a chain 101 or the like passing over a guiding pulley 210. On the shaft. carrying the disk 102 is also fastened a worm wheel 103, which meshes with a worm 104 on an inclined shaft 105 that can be turned by means of a vhand-crank ,100. ln this :the holes 135, 135 in the parts 133, 133. 0n

the lever 100 is fastened in any known manner a bow 107 Jforming a part of a pair of parallel plow arms 109, which latter are pivotally connected with a draw bar 108 extending to the front of the machine frame. The two plow arms 109 are shown as made in one with two plowshares 110 adapted to preliminarily plow the soil on both sides of the row of beets 204, so as not only to loosen the soil, but also to heap up the earth, as is shown in Fig. 2.A The two shares 110 may be inclined inward` and downward for producing the said effect. means should be employed for varying at will the cross distance between the two plowshares 110, so as to leave a space between their edges slightly larger than the diameter of the beets. The heaping-up of the earth will facilitate t-he lifting of the beets 'as will be explained later. The head 215 has fastened in it a in 111 and carries a bridge 217. 0n both sides of the headl215 two shoes 112 are mounted to rock on the pin 111 and two adjusting screws 218, 218 are disposed in the bridge 217 for adjusting the two shoes. Two arms 113 are secured to, the shoes 112 in any known manner and are provided with plowshares 114 for further loosening and heaping up the soil. By means oitK the screws 218 and by turning the hand-crank 10.6 the depth into which the shares 114 are to cut, can ,tbe adjusted Each plow, arm 113 has at the lower end a rear arm 115 to which is pivote-ily connected' a lifter 116. The lifter 11G/is in turn pivotally connected by means of a bent rod 117 (Fig. 3) with a lever 118 on the upper end of the arm 113.

Two parallel shafts 121, 121 (Fig. 3) are mounted in the machine frame to turn in opposite directionsand carry two opposite eccentrics 120, 120, the two straps 119, 119

Any known t of which are pivotall 1f (connected with the i two levers 118, 118 byineans of rods 119.'1 and 1197. Each rod 119b has an upper arm 129 bearing against the lower end of the corresponding rod 119i, whereby the fwo parts 119a and 119b are prevented from bending to the left in Fig.- 2. A hand-lever 132 is mounted in the machine frame to rock at 131 and has a' lower bent arm 130 with a cross head 1303, which letter is adapted to bear with two rollers 1301), 130b against the -rod parts 119% 119g, so that in this manner the three parts/119, 119A, 119b are maintained in their normal straight position and are ros able to positively move the armA 118 and by the rod 117 also the lifter 116. When, how-v ever, by pulling the hand-lever 13 2 downward the two rollers 1302130b are moved away from the rod parts 119, 119, then the parts 119, 119b of each rod can bend to thel right in Fig. 2 for permitting the lever 100' placed .oppositely, the two litters 116, 116

will reciprocate in opposite directions, so as to alternately push the beet 204: from opposite sides for effectively loosening the beet and'faeilitating its ascent. The two litters 116, 116 are rods of triangular cross section, so as to enable them to better cut downward into the soil and to strike the beet 204 from belowinstead of sliding on it. Preferably the two lifters 116, 11Glare made to converge rearward, so thatalso the smallest beets can be certainly seized and lifted. Each time that the beet 204 is knocked upward the loosened s oil will till up the space left by the beet, so that the beet is prevented from sinking and is `obliged to gradually rise from the s'oil, as is shown in F ig. 2. The levers 118 are provided with several holes and also the lower ends of the rod parts 1191), 119b so as to be able to adjust the several parts in their relative position. The above mentioned shafts 121 are driven in suitable manner, say from the right rear wheel 2 by means of a'chain gear 127, a shaft 125, chain gears 126, shafts 122, and bevel wheels 1222.

It will be seen that the soil is first loosened at both sides of a row of beets by the plow shares and that then the beets are slightly raised by the lifters, so as to facilitate their sides rof a row of beets,two bar's piyotally connected with said two plowshares and adapted to vertically reciprocate in the soil behind the shares, and means for rocking said two .bars in opposite directions so as to repeatedly push the beet from both sides in alternating directions for loosening and gradually lifting it.

2. In a beet-harvester, the combination with a frame, of two front plowshares in said frame adapted to preliminarily loosen the soil on both sides of a row of beets and to heap up the earth in this row, two rear.. plowshares in said frame adapted to plow the soil for further loosening and hea-ping it up, 'two bars pivotally connected with said two rear plowshares and converging rearward, and means for rockingV said two bars in opposite directions so as to repeatedly push the beet from both' sides in alternating directions for loosening'and gradually lifting it, the loosened and heaped-up earth lilling up the space left by the beet.

3. In a beet-harvester, plow shares for loosening the soil at both sides of a row of-v beets, beet-lifting members pivoted to plow shares, and means for rocking said JACOB BCKER members.
